As a Cornell grad, I'm frankly a little embarrassed by this post. How are you even thinking about grade deflation if you a 3.97? Do you want them to round you up to 4? And then giving generic application information as if somehow people on SDN will turn that into a concrete guarantee that you'll get into a top 20. I get that this process makes people a little neurotic, but for God's sake man, have a little self-awareness and self-control. It will take you far in medical school and life in general.
FWIW, I graduated with a 3.6 from Cornell and have 7 IIs, with multiple from the top 20s.
